Force aspx page to load from server--not cache

Discussion in 'ASP .Net' started by William LaMartin, Jun 21, 2008.

  1. I have an aspx page, A.aspx, that uses some xml. The source of the xml is
    another aspx page, B.aspx. B.aspx is populated with xml by code that
    depends on several Session variables.

    This all works fine the first time you load A.aspx. however, on subsequent
    times--with changed session variables--A.aspx is the same, as is B.aspx, if
    you check it. However, B.aspx is not really the same, since if you refresh
    the browser, B.aspx will then display the new xml as it should for the new
    session variables.

    How can I force the B.aspx page to not be produced from cache when it is
    requested by A.aspx? There is no HTML on it so I cannot use something like
    <META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">.

  2. I found the solution: Put the following vb code in the load event for the
    aspx page in question (B.aspx)

    Response.Cache.SetCacheability(HttpCacheability.NoCache
